+The last broad EBINIT field, `0x7843e`, is an authoring-only seven-value power tier. Its 243 rows do not
+partition by species, sex, defense element, or boss class, but values rise strongly with deployment cost,
+essence yield, level cap, and base statistics. Lily's three forms are exactly tiers 2/4/6, and recurring
+heroine boss definitions generally rise with their later, stronger appearances. The static corpus contains
+no read of this array, and the `/v2` native image contains neither its global index as an instruction operand
+nor as a little-endian constant. `unit_power_tier` is therefore curated at medium confidence as descriptive
+authoring metadata, not a runtime behavior claim. EBINIT now has specific names for 108 of 110 populated
+profile fields; only two suspicious one-record writes into runtime table `0x4e693/300` remain anonymous.
